An approach to systematically implement open-closed string duality for free large N gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganisation of the Feynman diagrams contributing to free field correlators. We also indicate why the resulting integrand on moduli space has the right features to be that of a string theory on AdS.

Nous résummons une approache systématique pour implémenter la dualité entre cordes ouvertes et fermées dans la limite de grands N des théories de jauge. Nous montrons comment l'espace des modules de la théorie des cordes fermées associée émerge de la réorganisation des diagrammes de Feynman contribuants aux corrélateurs de la théorie des champs libres. Nous indiquons aussi pourquoi l'intégrand sur cet espace des modules has les bonne propriétés pour être celui des cordes sur AdS.
